Fact, there use to be Viking farms on Greenland, meaning that at one time it was not covered in ice as it now is. That means that the world is now cooler than it was 700 years ago.
Fact, 100 years ago ships were able to navigate the northwest passage. That is not possible now because the northwest passage is covered by sea ice year-round. Does this not mean that temperatures in the 19th century were warmer than the temperatures of today?
Climate change does occur, it always has, and always will, but man's influence upon it is almost immeasurably small.
As for polar bears, they have existed for 500,000 years. During several periods of that time, there was no arctic ice, yet they survived. What does that tell you? It tells you that, unlike what you are being told in the news by politically biased reporters and so-called scientists, polar bears can exist in an environment without sea ice.
But, thankfully for the polar bears, the sea ice is not decreasing.
Am I getting through?

Well, I get you. You have some nice facts there.
Fact, the world has an ozone layer which is scientifically proven. It prevents too much heat from the sun to enter earth. I know that everybody knows this, but human pollutions from the last thousand years up to now have affected the so called ozone layer. That means that the heat temperature that enters the earth is much hotter than before, specially now that there's factories that directly dispose chemicals to the air.
